Best GPU's For Mining?

[Fademigo]

Anyone have a guide to flash bios of GPU? Tnx

You should be able to google up good guides on how to flash the BIOS of AMD 280X/7970 and 280/7950 cards,
and even 290 reference cards.
For newer AMD cards it is more difficult, although somebody just posted a way to undervolt the Sapphire R9 Nano card..
I am looking for a way to undervolt my R9 380X card by BIOS mod, but havent found anything that works yet.
Tried the Hedzin BIOS reader, but that wouldnt recognize my Sapphire Nitro 380X card..

Do you know a why to mod the XFX R9 390 cards? They consumes a lot of energy, so it is beneficial to reduce voltage.

Nope, sorry.
I tried to undervolt my own Sapphire R9 380X in Win 8.1 using Sapphire TRIXX, but gave up.

I used the Trixx to undervolt my R9 390. It is quite good to have -200mV core voltage change, but it has no aux voltage option.

Is there a GPU setup program that can change the R9 390 memory voltage? I mean the program such as MSI afterburner or Trixx?

[Fademigo]

You can use the HawaiiBiosReader to change the voltage of memory controllers. https://github.com/OneB1t/HawaiiBiosReader

You cannot use the MSI afterburner to change the voltages. It was possible for the 7970 or the 290.

The AMD R9 nano is the most efficient miners so far. It is even more efficient than the nVidia cards.

[Bemerand]

The AMD R9 nano is the most efficient miners so far. It is even more efficient than the nVidia cards.

But if you run the R9 nano at 1000MHz, its efficiency is lower. I am not sure if that is lower than the nVidia card.

[Vaccinus]

The AMD R9 nano is the most efficient miners so far. It is even more efficient than the nVidia cards.

yes and it cost 60% more lol

yes and it cost 60% more lol

Than nVidia cards? No way.

The nVidia cards that are on par with the nano regarding hash rate are even more expensive.


Anyhow, it's true though, core clock @ 1000, even with a heavy modified bios will still use up to much energy.

The holy grail setting (for me at least) is 800 core, 300 mem. Best Hash/power setting.

nvidia 970 cost around 300 now new, nano is 500, consumption is the same without your mod, or even worse for nano

i know you did get a discount for you nano, but that's not what casual miners will get, we must be realistic here

For the same consumption, I think the hashing of nano is higher. Even without mod, you just need to reduce the voltage in MSI afterburner.

True..

Dont' know what the hashrate on a 970 (Ethereum) is, but when mining with a nano (stock 1000 core) at -100mV in afterburner it will use around 4.9A (1000 watt) for 6 cards. 175-180Mh/s

I have a small feeling that a 970 isn't going to beat that...

[paradoxum]

With Eth prices tanking buy a Nano right now to mine Eth is a very risky proposition.  Used cards only or don't mine.

I just gave an example. There are other Algo's where the Nano is even efficient.

And, yeah, Eth is dropping, but Btc is rising. So it isn't weird that Eth is dropping

Which algorithm is more efficient for the nano compared to other cards? I am interested in mining with nano.

mine does 22 mega and with six card i'm consuming exactly 1k, but the overall hashrate is not 180, like the nano, but 132, so 25-30% loss, but they cost 40% less

also i think that the g1 gaming from nvidia is much more easy to resell than the nano, acerage gamers do not like to buy expensive card

My AMD R9 nano with undervoltage and underclock, with 6, it does 160MH/s, but with 800W power consumption.

Thanks for your efforts. I used your Nano mod, it works perfectly. I think the power consumption of the memory part is reduced a lot.

You're welcome, i'm still working on that part. Might get it even lower and stable

[Seast]

Any progress with the AMD R9 390 mod? The potential to save the power consumption is also big in this card.
